Download and run the PIA tool on the ePO server. The PIA tool is available both on the product download page, and the software catalog within the ePO console, under the ePO section.
IMPORTANT:
If the tool flags any errors, these errors must be addressed before you continue with the upgrade
Warnings must also be addressed if possible
All informational messages must be reviewed
The chart below contains a list of all checks that the tool makes for either:
If for some reason you can't use the PIA tool
Or

Eliminate unprocessed events:
Make sure that the DB\Events folder (including Debug) is empty or has minimal events stored before the upgrade
During the upgrade, this folder is scanned. If more than 10,000 events exist that are not processed yet, it interrupts the upgrade with a pop-up message stating:
This ePolicy Orchestrator server has more than 10,000 unprocessed events
NOTE: The above, might cause the upgrade process to take an exceptionally long amount of time.
